Problems solved by technology

Once the code is broken, however, i.e., a counterfeiter learns to duplicate a “signature,” this method loses value for authentication.
Nevertheless, to the extent that holograms ar...

Embodiment Construction

[0257]The detailed preferred embodiments of the invention will now be described with respect to the drawings. Like features of the drawings are indicated with the same reference numerals.

[0258]In FIG. 1, a substrate 1 with dichroic fibers 2 located on it is subject to a filter 3 of an incandescent lamp 4. A polarizer 5 is beneath a filter 6 underneath a camera 7 and this camera 7 via a Universal Serial Bus (USB) 9 is connected to a computer 11 which is in turn connected to a bar code scanner 13 via a RS-232 standard serial port 12. The bar code scanner 13 scans the bar code 14 on the substrate 1 and completes the authentication procedure with the aid of the computer 11.

[0259]FIG. 2 shows a thermal transfer ribbon 15 comprising a substrate 19, and positioned on the substrate 19 is a thermosoftenable coating 18 which comprises a layer 16 and a layer 17. Layer 17 comprises a sensible material, e.g. binder compounds. Layer 16 is crystalline, and has a melting temperature above the print...

Abstract

A method for authenticating an object, comprising determining a physical dispersion pattern of a set of elements, determining a physical characteristic of the set of elements which is distinct from a physical characteristic producible by a transfer printing technology, determining a digital code associated with the object defining the physical dispersion pattern, and authenticating the object by verifying a correspondence of the digital code with the physical dispersion pattern, and verifying the physical characteristic.

Description

FIELD OF THE INVENTION[0001]The present invention relates to the fields of authentication, security, anti-counterfeiting, and cryptography.BACKGROUND OF THE INVENTION[0002]The issues of authentication and counterfeit deterrence can be important in many contexts. Bills of currency, stock and bond certificates, credit cards, passports, bills of lading, as well as many other legal documents (e.g., deeds, wills, etc.) all must be reliably authentic to be useful. Authentication and avoidance of counterfeiting can also be important in many less obvious contexts. For example, improved verification / counterfeiting prevention mechanisms would be very useful in, for example, verifying the contents of shipping containers, quickly identifying individuals with particular health or criminal histories, etc. Counterfeit products are, by definition, unauthorized copies of a product, its packaging, labeling, and / or its logo(s). Attractive targets for counterfeiters are items with significant brand equ...
